-%% This module implements the meta tracer process belonging to the
-%% runtime component. Its main purpose is to write the ti-file (traceinformation).
-%% The ti-file contains translations between process id:s and what ever "you"
-%% want to read in the merged and formatted logfile.
-%% This process interacts with the runtime component process.
-%%
-%% Currently it handles the following types of ti-files:
-%%   Plain raw, binary log.
-%%   Relay to other inviso_rt_meta process on another node.
-%%
-%% The TI file will be on binary format and each entry is:
-%%   <<LengthIndicator:32, {Pid,Alias,Op,NowStamp} >>
-%%       Pid=pid(), or if OP==unalias pid()|any_other_than_pid()
-%%       Op=alias|unalias
